DISPLAY-RACK.

SPECIFICATION forming part f Letters :Patent N0. 562,532, dated June 23, 1896.

Application filed August 14, 1895 To all whom it may concern.'

Beit known that I, FRANK E. l-IARTZELL, of Alliance, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Display-Racks; and I do h ereby declare the following to be a full, clear, and exact description of the invention, such as will en able others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in display-racks and it consists in certain novel features of construction and combinations of parts, as will be hereinafter more fully described, and pointed out in the claim.

In the accompanying drawings, Figure 1 represents a view of my invention. Fig. 2 is a detached view of the clamp employed thereon. Fig. 3 is a view of another form of my improvement, and Fig. 4 is a detached view of the clamp employed thereon.

A represents the base, and 1 the upright supported therein, which latter may be of any desired shape in cross-section and of any suitable height. -The base A is provided with a suitable number of holes for the reception of screws or nails, through the medium of which said base may be secured to a iloor or other object. Upright 1 is adapted to support any number of bracket-arms 2, which latter are adjustably supported thereon through the medium of clamps 3. These clamps are each composed of sections 4t 5, hinged together, as shown at 6. The central opening, formed by bringing both sections of the clamp together, corresponds to the contour of the upright around which said clamps are to be secured. These clamps are locked on the upright by means of a tongue 7, one end of which is pivotally secured between the ears 8 integral with section il, while the opposite end thereof is adapted, when the sections are closed, to swing between the ears 9, carried by section 5. The outer end of tongue 7 is screw-threaded to receive a thumb-nut 10, by means of which the clamps are locked on the upright against accidental displacement. The side face of section 4 of each clamp is provided with a serrated face 11, which latter is adapted to mesh with a similar face carried by the bracket- Serial No. 559,217. (No model.)

the inner wall of said section, while the screwthreaded end thereof projects sufficiently beyond bracket-arms 2 to receive the thumbscrew 13, by means of which said arms are locked in any desired position.

When itis desired to support two bracketarms from one clamp, as shown in Fig. 3, the outer face of section 5 is also provided with a serrated face 14, as shown in Fig. ll.'

By employing clamps of the construction described, it will be seen that the brackets supported thereby may be moved up or down on their respective uprights, or the arms of said brackets may be adj usted to any angle of inclination desired. p

It is evident that changes in the construction and relative arrangement of the several parts might be made without avoiding my invention, and hence I would have it understood that I do not restrict myself to the particular construction and arrangement of parts shown and described; but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a display-rack, the combination with a support or upright, of a clamp comprising two members hinged together and constructed to embrace the support or upright, and a tongue hinged to one member and adapted to swing-between a pair of jaws formed in the other member and a thumb-nut on said tongue, one of these members having a serrated face, and an arm having notches formed in its upper edge and providedwith serrations which correspond to those on the clamping member and means for holding said parts adjustably together, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscrib- J. F. REHM, J. W. CEAINE.
